A glow stick contains a glass vial with chemicals. When the glow stick is bent, the vial breaks and the chemicals react to produce a glow. A science student observes
that a glow stick kept in the freezer glows for a longer duration than a glow stick
kept at room temperature. What conclusion can be drawn based on the observation?
Be sure to note the outcome and test variables in the conclusion. (10 points)

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

girl imma just put my comment here because i need a couple point okurrttt

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
